Wolff's Law

An important aspect of the human body's ability to continually reinvent itself is known as Wolff's law. This physiological law states that bone will remodel along lines of mechanical stress. In other words, weight-bearing activities such as walking, running, and strength training will cause long bones, lumbar vertebras, and the pelvis to become denser and stronger. Of course, the negation of this relationship is also true. If we don't engage in regular, vigorous weight-bearing exercise, our bones will lose mass and become weaker, less adaptable, and more liable to injury.

Regular chiropractic care helps us be more involved in our exercise activities. By detecting and correcting structural misalignments, especially in the spine, regular chiropractic care helps us function at peak physiological capacity. As a result, we're assisted in getting the most out of the time we spend exercising, both in terms of muscular development and building strong bones.

The seasons change and so do we. Superficially, it may not appear as if we're undergoing perpetual metamorphosis, but we are. Just as trees replace their leaves and birds shed their feathers, we too change dramatically. But our modifications and upgrades take place beneath the surface. Unlike leaves that turn and fall with colder weather, our alterations are hidden from view and we generally take these parallel life cycles for granted.

We may categorize our physiology in terms of systems, organs, tissues, and cells. Systems include cardiorespiratory, digestive, musculoskeletal, endocrine, lymphatic, and reproductive mechanisms. Corresponding organs include the heart and lungs, stomach and intestines, bones and muscles, the liver, pancreas, and thyroid and pituitary glands. Each organ is comprised of tissues and tissues are composed of cells. Although not an exact comparison, we could consider that a leaf is a cell of a tree. In that case, we could say that our cells are analogous to leaves.

Our cells perform complex functions, depending on the nature of their specialization.1,2 Cells have inputs in the form of nutrients and oxygen and outputs in the form of useful work (energy), as well as specific biomolecules they have manufactured and the waste products of such metabolism.

Cells wear out over time and must be replaced for the living organism to survive. Such replacement takes place continuously, a systematic process that itself requires substantial planning, signaling, and resources. For example, human red blood cells live for approximately 120 days. Thus, your entire supply of oxygen-carrying red blood cells is replaced every four months. Cells lining the stomach have a lifespan of about five days. Cells lining the alveoli of the lungs have a lifespan of approximately one week.

The coordination necessary for these life-and-death activities is the responsibility of the nerve system, the body's master system.3 The nerve system provides instructions for the proper functioning of all the cells in your body and processes information received from these cells. The massive complexity of the nerve system requires timely and accurate transmission of all signaling. Regular chiropractic care helps ensure that your nerve system gets the job done. As a result, regular chiropractic care helps ensure that the critical processes of the cellular life cycle are performed appropriately, and helps ensure our ongoing long-term health and well-being.
